What mass of H₂O is produced when 0.400 moles of KOH react completely in the following equation? KOH + HCl $\rarr$ KCl + H₂O

Question

Quizplus · Accepted Answer

The balanced chemical equation is KOH + HCl → KCl + H₂O. From the equation, 1 mole of KOH produces 1 mole of H₂O. Given 0.400 moles of KOH, it will produce 0.400 moles of H₂O. The molar mass of H₂O is approximately 18.015 g/mol. Therefore, the mass of H₂O produced is 0.400 moles * 18.015 g/mol = 7.206 g, which rounds to 7.21 g.
